I believe this will help to cear-up the bracket issue, you are missing the retainer/shroud piece.
(top right of image attached).

Also, one of the things to check (when you eventually strip your Strombergs down to clean / inspect them - they tend to accumulate varnish and gum that retards the suction chamber movement) is the rubber diagphram (circled in red) in each carb for tiny cracks (especially if using an ethanol-blended fuel). If they don't hold vacuum, you will have very grumpy carbs indeed!

Very interesting. I think I saw the outer curved screen portion amongst the loose parts. I will look. It still looks like the bracket sits at an angle by the looks of the filter holes in the bracket?

Looking closely at the scan from my parts manual, you can see that there are two options for bracket types. The one on the top right (that you have) is marked as being for fitment in the boot (trunk) while the one in the lower left corner is the bracket for fitment in the engine bay (on the valance). Since I am in Australia, I can only speak to to how I have seen "our" cars configured (which in some cases may differ to yours). But from my experience, the earlier Series 1 cars had their filter bowls mounted up front in the engine bay, on the valance, just under the air filter housing (passenger side of a US LHD car). This is the type with the "shut off" tap that yours appears to be. The later cars had their bowls in the boot (trunk) and use the simpler bracket for mounting in the spare wheel well. this revised type of bowl did not have the shut off tap included. I hope these two pictues may be helpful.

Early Series 1 location (with tap).

Late Series 1 location (no tap).

Interesting that your first image had "filter in boot"? I am flying home today and will explore this week!

Imperialmotorcars, i found the curved shroud! I have to run with your first diagram which shows it "in the Boot" Still a little flumaxed as to why the holes are drilled at an angle. Any thoughts there?

That's great news for you that you have the shroud; would be an "interesting" journey chasing one of those down nowadays! As for the location of the holes, all I can offer is to remember that components like this were "bought in" from suppliers, not made by Jaguar themselves and this is often the reason that sub assemblies like this may have surplus holes (for when they are sold to and mounted in other brands of cars of the period). Try to think of it as an early approach to multi-fit parts. Ultimately, since the diagrams show conflicting versions of where yours locates, it will be by looking at the holes drilled in both the "boot" spare wheel well wall and the engine bay valance and matching those to your filter housing; that will confirm where it was originally fitted by jaguar. Of course, whether you choose to leave it in that position, is up to you; it is, after all, your car.

Mekon I agree.

I keep a detailed log book and average around 20mpg around town, 22>24mpg on a trip. Car tuned for performance as I like to get were I am going and enjoy the drive.

Landfall, I too am a great lover of the much-underappreciated Series 2. I bought mine in 1987 and am still driving it. It has been a source of constant joy my entire life. Just curious, is yours running Zenith-Stromberg CD2 carb's or SU HS*'s?

Hi,

I took the Zenith-Stromberg's off although they were performing excellently and swapped them for a pair of new HIF4's (1 3/4") jetted them for performance and have been very happy.

The car has been an absolute joy to own and is used for any long journeys we may undertake. A long journey here in Australia is a daily run in excess of 300km's, comfort, handling, speed and safety is our criteria and the Jag meets them all.

Great job, the HIF is a terrific carburettor; almost , in a way, like mating an SU and a Zenith. I can't wait to visit Tassie, I have never been down your way, but always wanted to. I've made a promise to myself that once the virus is gone and my 3.8 Mark 2 is back on the road (fitting original power steering from an S-Type donor and a full bare-metal respray) a long and long-awaited drive down the East Coast and across on the ferry to Tassie will be the reward!

You won’t regret it for a second. The roads are a car enthusiasts dream, not to mention the scenery.

The other plus is the complete lack of police, you have to be unlucky to meet on in dire circumstances. As a visitor you would probably receive a caution anyway should you get carried away.

we used to have a Mk 2 way back in the 70’s gave it a work over for more performance, fond memories hence the Series 2 which I think once maintained is a hugely underrated car.

Thanks Landdfall,
You paint a vivid and exciting picture. It is great to know that my allergy to speeding tickets is unlikely to be aggravated around Tassie! Part of the plan is to tow a classic "teardrop" camper in full '60's kit along behind the Mk2; so planning a late Summer-early Autumn timing for the trip... the month is easy, but the jobs list means I haven't quite nailed-down the year yet (wink).
I couldn't agree with you more about the XJ Series 2, in properly-maintained and unmolested form they are (at least to me) the perfect Jaguar - at a tecnology level that they still feel like a true classic, but ahead of their time enough that they handle modern motoring with ease... the perfect balance! Never happier than when I am behind the wheel of mine... nothing else drives like one!

Keeping it as close to original as possible.

Have since changed 15" wires to these 16" mini lites.

The wires are for sale if anyone is interested. $1,000 for five, they are in good condition, the spare has never been on the road.

Landdfall,
I have to say that you have impeccible taste in car and colour, since this was my late-father's '78 Series 2 that he adored for over 25 years! Wires and wheel change included... great minds etc! But I will stop dreaming of Tassie, because Idon't want to hijack DBaer's thread... I am eager to hear the latest on his car...

Landdfall,

Where did you source the 16" Mini Lites?
